Transcript of 7.02 Respiratory, and Circulatory Systems

Journey of a red blood cell By: Tiffany Endy The start The red blood cell starts its life at the bone marrow. It is there along with its siblings (the white blood cells, and the platelets.)

The Red blood cell is especially made with hemoglobin to attract oxygen. Luckily the red clood cell does not use cellular respiration. Through the blood after coming out of the bone marrow the red blood cell makes its way into the blood taking up most of the space, along with plasma. This blood makes its way through the vein capillaries, and eventually the arteries. This new deoxygenated blood is ready to be filtered by the heart. In the heart Now the heart is ready to send this blood for pulmonary circulation to the lungs. To the lungs Now at the lungs and in the aveoli the red blood cell has picked up the oxygen it needs to carry also witnessing what carbon dioxide is. Now this oxygenated blood is sent back to the heart. Back to the heart Now this newly oxygenated blood is filtered through the heart, and sent throughout the entire body, brains, and all in what is called systematic circulation.
And now its job is done. The end Well not really. this little red blood cell will keep doing this for the rest of its life to keep the human body functioning right.
